Kicking a man while he’s down

There's no other way to describe what this Henderson police officer did in this video. Yet so far the city of Henderson refuses to give citizens the specifics of their review.
It grinds my teeth to read stories like this in which our government refuses to give us the basic information we deserve -- like the names of all the officers involved and outcome of the internal police investigation. After all, this video just cost Henderson taxpayers a fair chunk of change. We ought to know more than we do.
You can see the video for yourself and make up your own mind. For me, the officer who steps in and unnecessarily kicks the man in the head while he's down displays poor judgment, maybe even to the extent of costing him his job. Was that considered? If not, why not? If we're unlucky enough to get pulled over in Henderson for a traffic violation today, are we in danger of running into this guy and getting our heads kicked, even if we comply with every command?
You also can read the latest story here. Stop stonewalling, Henderson. Treat people with a little more information and dignity than this.
PS: Henderson PD has not revealed the name of the head-stomping police officer. You can find it here. Still not as forthcoming as the department and the city should be.
